Error in Figure
In the original publication [1], there was a mistake in Figure 1. In Figure 1d; the color scheme of the shown samples (an untreated graphite rod and a graphite rod pretreated anodically in 1 M NaOH for 10 min) was inversed as stated in the figure caption. The corrected Figure 1 appears below.
Figure 1.
(a) Front (left) and top (right) sides of the electrochemical exfoliation set-up. The lateral view shows the cooling system and the power supply while the top view pictures the electrodes’ position in the electrochemical reactor. The dimensions refer to a 1600 mL reactor. (b) Production protocol for the up-scaling process with anodic pretreatment in 1 M NaOH. (c) Cyclic voltammetry applied to a graphite rod in 1 M NaOH (scan rate 10 mV/s; 6 cycles: dark green to light green). (d) Cyclic voltammetry applied to a graphite rod in 1 M H2SO4 (scan rate 10 mV/s; 6 cycles: dark color to light color). Red indicates an untreated graphite rod and blue indicates a graphite rod pretreated anodically in 1 M NaOH for 10 min.

The authors further wish to revise reference 1 with the corrected format: 1. Directorate-General for Research and Innovation (European Commission). European Green Deal: Research & Innovation Call; Publications Office: Luxembourg, 2021.
The authors apologize for the mistake and state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
